Hantz reactions, also known as Hantzsch reactions, refer to a series of chemical reactions that involve the synthesis of dihydropyridines. These reactions are named after the German chemist Heinrich Hantzsch, who developed the method. In its most common form, the Hantzsch reaction involves the condensation of aldehydes (or ketones), β-ketoesters (or certain other carbonyl compounds), and ammonia or primary amines in the presence of a reducing agent.
